The US is a big country. SS specs are not that special anymore, but I am not sure who can do them. Larry Eckler (Morgan Spares) I am sure could handle this. Pierre Brun (BabyDoll Mechanic) can do this - Salem, Oregon. But if you are dead set on SS Spec's, I am not sure there are many alive. Bob Bowie, Massachusetts might know of somebody.
Let Me know if You need anymore help and I will do some more research.
